Steatotic Liver Diseases: What You Should Know
Steatotic liver disease (SLD) has been proposed by multinational liver societies as a new nomenclature for fatty liver disease. This change from the widely used term nonalcoholic fatty liver disease (NAFLD) aims to define the disease category by inclusion criteria rather than excluding several conditions, to focus on its pathophysiology related to metabolic dysfunction, and to defuse the stigma caused by the terms fatty and alcoholic. SLD has several subcategories: Metabolic-Associated Steatotic Liver Disease (MASLD) and Met-ALD, which bridges the gap between non-alcoholic and alcohol-associated liver disease (ALD). Ultrasound has historically contributed a lot to this disease that would remain the same. During this session, Dr. Tateishi will clarify as well as guide you through the future prospect of this new terminology, including the expectation to the ultrasound examination as a hepatologist.

Multiparametric US for the evaluation of MASLD
An early and accurate detection of liver steatosis is important because metabolic dysfunction-associated steatotic liver (MASLD) is associated with several metabolic comorbidities that are the risk factors for cardiovascular diseases. Moreover, the literature suggests that fibrosis progression may occur not only in patients with metabolic disfunction-associated steatotic hepatitis (MASH) but also in those with “benign” liver steatosis. Therefore, tools that non-invasively assess liver fat content and liver fibrosis are of great interest not only for the diagnosis but also for follow up and prognostication. Algorithms for a quantitative estimation of liver fat content are commercially available and most of them are based on the evaluation of the US attenuation coefficient. Multiple clinical studies, mostly performed with ATI (Canon Medical Systems), have demonstrated good accuracy and reproducibility of these new algorithms for fat quantification. Since a few years, liver stiffness assessment with the shear wave elastography (SWE) techniques is considered a reliable substitute of liver biopsy in several clinical scenarios, including MASLD. Guidelines regarding the use of the SWE techniques for the staging of liver fibrosis have been released. For the US evaluation of MASLD, scores that combine US parameters have also been recently proposed.
